Eric Sabety –
A tremendous labor saver.
Runs like a champ. Pounds rebar into degenerate granite. Breaks up cement. Powerful. Batteries are big. Instead of calling China our enemy maybe our politicians should study what China is doing right. Singapore is their model. This company makes a lot of other brands as well. From the battery it looks like they might be making Milwaukee tools.

Excellent value for home user
As a first time sds user am impressed with the power of sds bits to penetrate concrete compared to a regular cordless hammer drill with chuck. The possible drawback of not accepting regular bits can be overcome by getting an sds drill chuck adapter for non hammer use only. Could drill about 10 1/2″x6″deep holes in hammer drill mode before the battery was down to 50% or 2 out 4 LEDs. This is probably when I am ready for a break. The charger shows a red light when charging, green steady when charged, and green blinking when battery is removed. The battery 4 bar led is a nice indicator of remaining charge. Like almost all tool brands this uses a unique style of battery. It would be an advantage if you could interchange batteries.

Just as good as Bosch
I owned a Bosch 18V rotary hammer drill and it got stolen from my truck. So I was very reluctant to buy this inexpensive drill but figured I couldnât go wrong with the Amazon return policy. Well it didnât disappoint, the drill is just as powerful and if not even more powerful than my previous one. The battery also lasted unexpectedly long on a job site. Overall a great purchase! Now I just hope it lasts a while without breaking down.

Light weight and did its job
I was thinking of buying a Milwaukee, but for the price, why not try it?It gets the job done. Battery life is good, so far, and it makes 13 holes of 3/8 with 3 inches deep.

Occasional use
It is a nice quality product. The only thing is that it is too light for my use, The battery depleted pretty quick and it takes a little north of two hours to fully charge it again. If you intend to use it on an occasional basis, go ahead and purchase this, it is perfect. If you are like me, Contractor either purchase another battery or go with a corded product

Not a chuck style bit holder.
I thought i’d be able to use any bit with this but it’s built differently. They are meant for ends that can lock in like a quick connect. Unfortunately this limited me too much for the things I use my hammerdrill for. I will not be able to use this effectively.
